Cutting the fibre optic connecting costs by half Fujitsu Laboratories Ltd and Furukawa Electric Co Ltd have collaborated to develop a new multi-fibre optical connector to join and align multiple optical fibres for optical interconnects. The conventional method of connecting optical fibres is an expensive process, requiring high-precision polishing to align the tips of the fibres. Fujitsu Laboratories and Furukawa Electric have developed a connector that can accommodate different lengths of optical fibre and which, with a spring mechanism that obviates the need for the polishing process, will cut the costs of connecting optical fibres by half. This new connector is said to achieve performance on a par with conventional connectors while simplifying the task of installing high-capacity optical interconnects. It is anticipated that the technology will increase data transmission speed between boards, so increasing overall server performance. Furukawa Electric Co Ltd – Japan Website : www.furukawa.co.jp

example, download speed can be 300Mbps if the upload speed is reduced to 100Mbps. KT’s FTTH-G solution saves building owners the cost of replacing copper wires with more advanced cables, the company said, and it will run a pilot project for the technology in some older apartment buildings in Gangnam district to demonstrate the service. “We will further enhance FTTH-G and create a technology that provides at least 300Mbps Internet speed next year,” said a KT official. “We will utilise various types of wires and enable old buildings to provide Internet at giga- bytes-per-second speeds.” KT Corporation – South Korea Website : www.kt.com

KOREA’S KT Corporation has developed technology to enable copper telephone cables to provide Internet service at speeds “never before accomplished”. The company exhibited its technology during the Mobile World Congress at the end of February. Many old buildings still use copper telephone cables with optical cable or unshielded twisted pair (UTP) cables to provide an Internet service, but services through copper wire using VDSL (very high bit-rate DSL) are limited to 100Mbps. KT has announced its FTTH-G solution, said to provide a two-way service of at least 200Mbps using a pair of telephone lines. KT said download speeds could be much faster than 200Mbps. For
